Tiarella, photo by Harold Davis. View this photo larger.

This is a tiarella, a variety of saxifrage, a small plant known for growing between rocks and breaking up stones. Saxifrage is also notable as the first name of a sympathetic “green” scientist in Kim Stanley Robinson’s epic Mars Trilogy.

I photographed the small universe of this flower against the glow of the rising sun last month using the technique and in the circumstances I described earlier (along with another, related capture).
